Definitions

  • the present invention relates to a dynamic pendulum stool for isometric contraction of the muscle groups of the lower limbs and the abdominal belt in a sitting position.
  • This type of office chair has the disadvantage of not soliciting the muscles of the legs and back so that users of these seats risk degeneration of the spinal muscles and vertebral damage such as the wear of the discs due to bad posture.
  • Pezzi® In order to have a good posture, it is well known to use a ball "Pezzi®” for example. These Pezzi® balloons allow a user to sit on it and work the muscles of the legs and back.
  • Electro-stimulation devices are also known which allow isometric contraction of the leg and abdominal muscles; however, they are difficult to implement especially in an office, the establishment of the electrodes requiring in particular to undress.
  • German patent application DE 2314717 which describes a seat having two ball joints provided with springs in which the user is in unstable equilibrium so that he can return to a normal position by means of a lateral deflection by an active leg play.
  • the German patent application DE 19533558 describes an active-dynamic seat comprising a foot which has a curved base surface, concavity facing upwards, to allow a tilting movement, a column secured to the foot and a seat mounted at a fulcrum to the upper end of said column.
  • the curved base surface of the foot rests directly on the ground and has a spherical curvature in at least a partial area.
  • the seat is mounted at its fulcrum so that it can tilt on all sides. Said fulcrum is either below the center of curvature of the base surface or adjustable within a height range whose lower limit is below the center of curvature and the upper limit of which is below the center of curvature.
  • the seat is mounted on a connecting element consisting of an elastic spring element and bearing on a support integral with the upper end of the column.
  • One of the aims of the invention is therefore to overcome these drawbacks by proposing a dynamic pendulum stool of simple and inexpensive design and allowing isometric contraction of the muscle groups of the lower limbs and the abdominal belt in a sitting position.
  • a dynamic pendulum stool comprising a foot, a column secured to said foot and a seat secured to the upper end of said column, remarkable in that the column consists of a telescopic column having a lower portion integral with a spherical foot having a diameter of less than or equal to 20 cm and an upper portion whose free end is provided with a hinge having three degrees of freedom and secured to the underside of the seat, so that, when a user is supported on the seat, the column forms an angle of between 30 and 90 ° with respect to the horizontal, thus allowing isometric contraction of the muscle groups of the lower limbs and the abdominal belt. sitting.
  • the device according to the invention has a very small footprint allowing a specific use, replacing a conventional office chair, or continuous and providing, during use, isometric contraction of the muscle groups of the lower limbs and the abdominal belt.
  • the lower the angle of the column with the horizontal the greater the work of the muscle groups of the lower limbs.

  • the telescopic column (2) consists of two circular section tubes, a first tube forming the lower part (2a) provided at its lower end with a threaded rod (4) extending coaxially with said tube and, at its upper end, a quick clamp (5), and a second tube forming the upper part (2b), said second tube having an outer diameter just smaller than the inner diameter of the tube of the lower part in such a way that the upper part (2b) can slide in the lower part (2a) in order to be able to adjust the length of the column according to the user's morphology and / or the desired difficulty of working on the muscles of the muscles. lower limbs as will be detailed later.
  • the fast clamp (5) consists, in a manner well known in itself, in a substantially open annular part whose free ends are connected by a tie rod, one of whose ends cooperates with clamping and tensioning means under tension of said pulling.
  • Said clamping and pulling means consist of a handle comprising a cylindrical head rotatably mounted about an eccentric axis parallel to the axis of the tubes.
  • the tubes forming the lower part (2a) and the upper part (2b) are advantageously obtained in an aluminum alloy or any other light metal alloy well known to those skilled in the art so that the stool following the invention is the lightest possible.
  • telescopic column (2) may be substituted by any other telescopic column well known to those skilled in the art without departing from the scope of the invention.
  • said foot (1) has a spherical shape obtained in a non-slip material, and preferably in an elastomer, in order to prevent the next stool the invention does not slip on smooth floors such as on tiles for example.
  • Said elastomer may consist of any known natural and / or synthetic elastomer such as natural rubber, synthetic polysioprene, polybutadiene or styrene-butadiene copolymer for example.
  • Said elastomer preferably has a shore hardness greater than or equal to 40 in order to avoid crushing of said foot (1).
  • the spherical foot (1) comprises a sleeve (6) extending radially and provided with an internal thread (7) cooperating with the threaded rod (4) integral with the lower end of the lower part (2a). of column (2).
  • said spherical foot (1) has a diameter less than or equal to 20 cm in order to limit the weight of the stool and to allow greater angular variability.
  • the seat (3) has a substantially parallelepiped shape whose width is substantially equal to the width of the basin of a person of average weight.
  • the upper part of said seat (3) has a resilient layer (8) to improve comfort.
  • Said seat is articulated to the upper end of the upper part (2b) of the column (2) by a hinge (9) having three degrees of freedom.
  • said articulation consists of a ball joint comprising a seat (10) integral with the lower face of the seat (3), in its central part, and receiving a ball joint (11) integral with the end free upper part of the upper part (2b) of the column (2).
  • the seat (10) of the hinge (9) is secured to the seat (3) by a threaded rod (12) integral with said seat (10) and cooperating with a thread (13) formed in said seat (3).
  • a threaded rod (12) integral with said seat (10) and cooperating with a thread (13) formed in said seat (3) In this way, it is easy to quickly change seat (3) according to the preferences of the user in particular.
  • ball joint can be substituted by any other joint well known to those skilled in the art, such as a ball joint or the like, without departing from the scope of the invention.
  • the seat (3) may have any shape and / or include a side or front handle without departing from the scope of the invention.
  • the stool according to the invention may also include a damping system of the gas spring type or spring inserted in the lower part (2a) and / or upper (2b) of the column (2) to improve comfort use of the stool according to the invention.
  • the stool according to the invention causes an isometric muscle contraction of the twin muscles, ischia-temples, quadriceps, glutes, lumbar and absidial dorsal muscles.
  • the isometric muscular contraction is achieved by a work of proprioception and equilibrium of the user which compensates the instability of the stool.
  • the articulation of the seat (3) on the column (2) and the sole point of support of the spherical foot (1) provide a lateral inclination, front and rear which forces the user to have a position stable in which the line of the shoulders is parallel to that of the pelvis, a support on the feet causing the isometric contraction of the muscles of the lower limbs and an unstable gluteal support which is compensated by the proprioception and the contraction of the lumbar and abdominal muscles.
  • said stool is constituted in the same manner as previously of a foot (1), a column (2) integral with said foot (1) and a seat (3) integral with the upper end of said column ( 2).
  • Said column (2) consists of a telescopic column comprising a so-called lower part (2a) integral with the foot (1) and a so-called upper part (2b).
  • the telescopic column (2) consists of two tubes of circular section, a first tube forming the lower part (2a) provided at its lower end with a threaded rod (4) extending coaxially to said tube and, at its upper end, a quick clamp (5), and a second tube forming the upper part (2b), said second tube having an outer diameter just smaller than the inner diameter of the tube of the lower part in such a way that the upper part (2b) can slide in the lower part (2a) in order to be able to adjust the length of the column according to the user's morphology and / or the desired difficulty of working on the muscles of the muscles. legs.
